How Durable Are Solar Powered Lights?
Solar lights are popular for power conservation and low maintenance. They are also deemed to be rather durable. So, how long will your solar lights [http://yoursolarlights.com/] last? Well, there are three factors that will influence their longevity: batteries, bulbs, and solar panels.
Batteries. Most solar lights are equipped with double or triple A rechargeable batteries powered by the sun through solar panels. As you probably know, rechargeable batteries tend to lose their recharging capability - usually within about 2 years. When you notice that your lights are not performing as they should, do not panic - most likely you just need to replace the batteries.
Bulb. Most solar powered lights in the market today use LEDs, though you still might find some with incandescent or fluorescent bulbs. Generally LEDs are quoted to last about 100,000 hours; which is about 100 times more than regular bulbs. If you translate this into years, you will get roughly 10 years of normal use. And of course, unlike incandescent bulbs, LEDs will not suddenly go out, but rather fade gradually. This will give you an idea of when you might want to replace them.
Solar Panel. Solar Panels typically used in solar lights are essentially silicon semiconductors. They tend to degrade due to sun exposure. However, if not directly damaged, it will take a long time for them to become unusable. You might see some solar panels functioning for 20-40 years.
Here are the conclusions I made. Out of all three factors, solar panel is the most durable and, therefore, almost a non-factor. Rechargeable batteries will fail the fastest but they are typically easily replaced to bring your solar lights back to full capacity. That leaves the bulb as the main solar powered light longevity factor. My suggestion is when the LEDs do not shine as bright as you desire, it is time to look for replacements. Good news is, in 10 years you might want to change your decor anyway.
Batteries. Most solar lights are equipped with double or triple A rechargeable batteries powered by the sun through solar panels. As you probably know, rechargeable batteries tend to lose their recharging capability - usually within about 2 years. When you notice that your lights are not performing as they should, do not panic - most likely you just need to replace the batteries.
